A rod of length 200 mm & 5 mm in diameter with thermal conductivity of 400 W/mk is fixed between two walls each at a temperature of 130°C. Rod is exposed to surrounding at 30°C with a heat transfer coefficient of 40 w/m2k. Find the temperature of the mid point of the rod in °C (round off to one decimal place)
Enter numerical value using the virtual keypad. Round off where necessary.
